处理锚雷方式之一是在雷链上挂放装填炸药的爆破筒,依靠爆炸将雷链炸断使雷体上浮。水下爆炸是一种复杂的现象,而雷链在水下的受力也很复杂。通过理论分析,数值仿真来研究炸药水下爆炸对雷链的破坏机理。研究表明炸药爆炸后产生的冲击波先后作用在各链环上,使得雷链承受横向剪力,同时雷链两端又加上约束,导致离炸药最近的链环在多重力作用下,与相邻链环相交区域发生断裂。通过对炸药处理雷链进行研究,为以后进行处理雷链的装药设计提供帮助。
One of the ways to deal with the anchor mine is to hang a blasting cylinder filled with explosives on the mine chain and rely on the explosion to blow up the mine body. Underwater explosions are a complex phenomenon, and the force of the chain under water is also very complicated. Through theoretical analysis and numerical simulation, the failure mechanism of underwater chain explosion on the chain is studied. The results show that the shock waves generated after the explosions explode one after the other on the links, which make the laths withstand the transverse shear force, and the two ends of the lash chain are restrained again. Under the action of multiple forces, Fracture occurred at the intersection of the links. Through the research on the explosive chain, it can help to design the charge of the chain in the future.
